Q & A

The national average cost to clean windows is $120-$170. Typically, window washing for commercial spaces costs less per window than residential window washing, but has a higher overall price because the greater number of windows. Commercial window cleaning companies may charge a standard rate per window — for example, $3 to clean the exterior only, with a higher rate of $4 or $5 to also clean the interior. There may be an additional charge, such as an extra $1 per window, for scrubbing off water stains or deep-cleaning window tracks. Double-hung windows require more labor and will therefore cost more to clean. Companies may charge a flat rate, such as $8 per double-hung window or $9 per French door, to account for the added work. Building height will play a factor in window washing costs. Standard cleaning for one- and two-story buildings will typically stay within the same range, but cleaning high-rise windows may entail special safety permits and equipment, which would increase costs. Your location will also affect window washing costs. Smaller towns and areas with a lower cost to do business will have lower window cleaning rates than large cities.
